NAME
nng_sockaddr_in6 - IPv6 socket address
SYNOPSIS
DESCRIPTION
An nng_sockaddr_in6 is the flavor of nng_sockaddr
used to represent TCP (and sometimes UDP) addresses,
including the Internet Protocol (IP) address and port number.
This structure is used with IPv6 addresses.
A different structure, nng_sockaddr_in, is used
for IPv4 addresses.
The following structure members are present:
sa_family-
This field will always have the value
NNG_AF_INET6. sa_port-
This field holds the TCP or UDP port number, in network byte-order. A zero value here is used when no specific port number is indicated.
sa_addr-
This field holds the IP address in network-byte order.
sa_scope-
This is the scope, and is typically used with link local addresses to identify a specific interface. The details of this are specific to the operating system. This value is presented identically to the underlying system’s, including any byte order considerations.
The sa_port and sa_addr fields are in network-byte order to
facilitate their use with system APIs such as inet_ntop().
Most platforms use some form of BSD-derived network API, which uses
network-byte order in the various structures (such as sockaddr_in6).

This field appears similar to BSD sockaddr_in6, but it is
not the same, and they may not be used interchangeably.
